There was a rumor last week that Apple was unhappy with Capcom over the way in-app purchases could be made in Smurf's Village. Turns out Apple may have had a very good reason to be upset.

The Federal Trade Commission has announced that it will be investigating the way in which "in-app purchases" can be made via Apple's handheld devices.

It seems FTC Chairman Jon Leibowitz is concerned that there is not enough security preventing children from inadvertently spending hundreds of dollars of their parent's money, and will also be looking at the way apps like Smurf's Village appear to be "free" and then aggressively market these in-app purchases.
